To all whom t may concern:

Be it known that I, Gusrav Enom, enlgineei, a citizen of the German Republic, and resident of Hannover, Germany, have 6 invented certain new and useful Improvements in Rigid Airahipa, `of which the folv lowingis a s cation;y

' My invention relates Vto air-ships of the kind'known as rigid air-ships; more espe io and the object of my invention is to improve the frame-work in such a way vas to make it vip tto answer all.requirements as regards strain, lsaving in weight, swimming capacit on wateigslight resistance to air and the 'ke ccording to my invention, the body of the rigid air-shi is composed of a. channelforming cent lnlgitudinal frame-work air-ship, and of cross-shaped transverse members or trelliswork -girdera connected with annular double circumferential body members dete wires connecting sai latter members with each other, the outer shape of the air-ship. The thus reduced sector-shaped compartments of t e frame-work form cells to house the gasbags which, enclosed by the staying or sti'ening wires of the inner circumferential body-members, form, in their entirety, the carrying body of the air-ship which is either torpedo-shaped or roll-shaped, the,

'ba bein correspondin' ly arra vin loiigitudial direction -ogf the bi as well as side by side horizontally and vertically, as will more fully appear from the detailed art 'of this specification.

Some Eorizontal cross-members are elongated laterally beyond the circumference of the frame-work, as are also some of the vertical ,cross-members thereof, but these 1at' ter parts are elongated only verticall downwards, not also upwards, whereas t e hori- Theselateral elongations form carriers for the motors and the propeller's, whereas the downwardly elongated parts of the vertical cially it relates to the frame-work thereof,-

4forming s. kind of b -bone or spine for the in .connection with zontal parts are elongated to both sides.V

the body-structure near the heacLo the xiii"-I` ship in the planen-6 OfvFimre 1z Fi Aire.

'members are connected with annular double,

circumferential members c c", c1 beingtlie inner parts, c the outer parts thereof. 4These annular members are connected with each other lengthwise ofA the air-ship, by par- 75 allel horizontal wires f which can yield inv a certain measure in the case of the air-shi setting somewhat hard on the ground? There are formed in this way quadrantshaped com artmnts g'which receive lthe 8U gaebags, v he bags inthe upper comparti?? ments may be connected by hoses with the bags in the lower 'compartments in '-order'to render possible a. compensation of the conof the bp. in-comparatively high alti a tildes. The Ii ed bags contact 'at their in?J ner'surfaces with diagonal wires It" exteiiding from the central ti'ellis-woik'to that at the outer sides 'of the body, and'atfthir other sides with the parallel wir s fextend- 90 ing from any of the annular cir' umferent-ial structural membersto its two neighbouring ones. ,A

lOwing to the' formation of `'ius'idigintshaped compartments for the receptionl of 91;' the gas-bags, or, in.othci words, owing to the arrangement' of quadrant-shaped gasbags in the longitudinal diiection. of the ship, as well as side bysidehorizontally and `vertically. the gas-pressure in the upper 100 bags acts -on the annular ciicumferent al 'structural body-members standing vertically relatively'thereto, and the gas-pressure in :the lower bags `which act independentlyof the upper ones acts on the horizontal parts 10P of the cross-shaped structural members, whereby a good buoyancy is warranted. Besides, owing to the gas in the upper and the lower bags pref-.sing also on the vertical parts of said cross-shaped structural body.- 1M members, Vthe vertical walls of the conipartd ments are anchored relatively to the neighbouring parts of the body structure where by the stability of the entire' structure is considerably improved.

The wires f connecting the parts c -of the annular circumferential structural members structures h connecting the suspended structure i with the lower longitudinal trellis'- work girder of the body. The horizontal elongations b of the members b carry the propeller-s j and their motors j. Owing to the stabilit of the air-ship being very great, the propel ers on its two sides may work s1- multuneously in opposite directions whereby Iquick turning is greatly fncilitated,`

rigid air-ship, comprising, in combination, a channel-forming central longi-I tudinal structure; crossshaped structures connected at their centre antl'vjith said longitudinal structures; dou le aniilnr circumferential structures connected'with the outer ends of said cross-sha d. structures', one :mnulus of each pair of t ese structures being located inside` the other one; lateral outer structures projecting beyond some of said circumferential structures and forming elongations of some of the horizontal members of said cross-sl1aped structures and `being adapted to carry the motors, downward y exten lng structures rejecting also beyond some ofsaid circumerential structures -and forming elongations of some of the vertical members of seid cross-sha structures and-bemghadapted to curr gtructnrgsnppggtmg cabins;

pro ellers and the.

wires connecting the inner annuli of the said circumferential structures with each other, and wires connecting their outer annuli with each other; gas-bags housed inthe gas-ce forming compartments formed by, and located between, said structural parts of the air-ship body, except said outer wires; and on envelelpe enclosing these parts and being support also by the said outer wires, substantially as set forth.

2. A rigid air-ship, comprising, in combination, a. channel-forming central longitu- Adinal structure; cross-shaped structures con.-

nected at their centre parts with said longitudinal structures; double annular circumferential structure connected with the outer ends'of said' crossshapedstructures, one annulus of each pair of these structures located inside' the other one; lateral outer structures -pro'ectng beyond some of said circumferentia structures, and forming elongations of some of the horizontal members of said lcross-she structures' and being adapted to carry t e Propellers and the moters; Propellers and motors attached carried by, said elongctions; down 4ardly extending structures projecting also youd some ofksaid circumferential structures and forming elon tions of some of ,the vertical members of said cross-sha d structures and being adapted to carry tie structure supporting the cabins; a cabin-carrying s l tures'uspended from these elongations, and cabins on this structure; Wires connecting the said circumfe ntial structures with each other; gas bags housed in the gas-cell forming compartments formed' by, and located between all said structural parts of the airship bo and an envelope enclosing these parts, su tantially as set forth. l
